To all whom it may concern.'

Be it known that li, THOMAS GILMonE, Jr., a citizen of the United States, and resident of the borough of Brooklyn, county of Kings, city and State of New York, have inventedcertain new and useful Improve'- rnents in Briqueting-Machines, of which the following is a specilication.

My inventipn relates to briqueting machines or presses and more particularly to machines or presses for briqueting metal or mineral fines through the medium of pressure and without the use of a binder of any kind. My improvement has for its object to provide a simple machine of the indicated type wherein the process of briqueting is reo ,eiiciently carried out, which works at low tonnage capacity and wherein the well known advantages of briqueting are brought within the reach of smaller foundries and industrial plants ordinarily incapable of installing and supporting the high capacity, expensive machines heretofore found neces sary to secure proper working. A further object of my invention is to provide a briqueting machine in which the diliiculties of feeding the material, packing it preparatory to the use of heavy pressure and rempval of the finished briquets from the machine which ordinarily exist in such machines, are entirely overcome "or at least reduced to a minimum. Other' objects of my improvement will appear from the description hereinafter and the features of novelty thereof will be pointed out in the appended claims.

In the accompanying drawings, which show an example of my invention for illustrative and descriptive purposes, Figure 1 is a plan view of my machine; Fig. 2 is a side elevation partly in section; Fig. 3 is a cross section on the line 3 3 of Fig. 2 and Fig. 1 is a similar View on the line 4 4 of Fig. 2.

As shown in.the illustrated example the machine or press comprises a pressure exerting mechanism 5 which may be of any suitable and well known type in which the pressure is subject to the desired control by the operator in any suitable manner. The mechanism 5 as shown may be connected with a source of power, preferably though not necessarily hydraulic, by means of a pipe 6, said mechanism controlling and operating' a plunger 7 of suitable dimensions and material and having apressure exerting or operative end 8; as shown in the drawings a crossfhead 7 and its coperating parts may be operatively connected with the plunger- The machine further includes a full mold 9 carried by suitable supporting means 9, and corresponding in cross-sectional form to the shape of the operative end 8 of the plunger 7. The illustration shows these elements as cylindrical which it is to be understood is not essential as any other desired form of construction may be substituted. In any case the operative end 8 of the plunger 7 is of a size adapted to fit the mold snugly or with what is commonly known as a sliding fit, the mold 9 being referably provided with a lining 10 of suitable material adapted to resist wear and reduce friction to a mini mum. A movable plate 1l normally forms the back of the mold 9 and controls the communication between the latter and an exit or discharge channel 12 as shown in Fig. 2. The plate 11 may be operated in the man ner and for the purpose to be more fully described hereinafter in any suitable manner as for instance by means of a lever 13 gether in spaced relation to cach other and against separation by means of bolts 18 and nuts 19, the bolts being located at opposite sides of the plunger 7 in parallelrelation with each other and with said plunger.

The machine further comprises a packing device which in the example shown coinprises a trough or receptacle 20 of semi-circular shape in cross-section and secured at its one end to said mold. support 9 and at its other end to a cross-bar 2l extending between and carried by the bolts 1S. The Cross-bar 21 may be fixed upon the bolts 18 in any desired manner as by means of clamping` devices 22 and in any case preferably extends beneath the plunger 7 so as not lo interfere with the operation thereof. The packing device referred to further consists of a movable cover 23 which in the illusv pivotally mounted upon a rod 14 carried by 1 with a sliding fit. It will of course be understood, if'the shape of the plunger end 8 and mold 9 is other than circular, that' the trough or receptacle 20 and cover 23 are constructed to form a cylinder having a corresponding cross-sectional form as will be apparent.

The cover 23 may be movable relatively to the trough 20 in any,desired manner and as shown is pivoted at 24 upon lugs 25l secured to or forming part of the trough 2O or cross-bar 21; in order to operate the cover 23 it may be formed or provided with a projection 26 to which arms 27 are secured for lnstance by means of bolts 28, said arms 27 in the illustrated example inclining upwardly and diverging from said projection as shown in Figs. l and 2. In order to facilitate the actuation of the cover 23 if supported and operated as shown in the illustrated example the arms 27 may be provided with counter weights 29 preferably adjustable thereon and secured in position in any suitable manner as by means of set screws 30. Any means suitable for the purpose may be used to lockthe cover 23 fin its operative position against movement relatively to the trough 20; for instance as shown the latter may be provided with upright lugs 31 between which a transverse projection 32 securedvto or formed on the cover 23 fits in the operative position of the latter. The lugs 31 and projectiom 32 are formed with apertures adapted to register with each other in the operative position of the parts and are arranged to accommodate and receive a bolt 33 which when'in position, serve s to lock the cover 23 in operative combination with the trough 20.n It will be apparent that the above are only 'examples and that..

. the cover 23 may be otherwisemovable relasired. In order to increase the in tively to the trough 20 than as shown and described and also otherftypes of locking devices either manually' actuated or by means of suitable power maybe substituted if degidity and strength of the cover 23 it may "provided with a rib 34 extending between the proj jections 26 and 32 as shown in Fig. 1.

When operatively set up the pressure exl ,er-tin mechanism 5 and mold 9 with iftsconi'ecte parts rest upon a suitable foundlion 35, with the common axis of the mold 9,

cylinder formed by the trough 20 and cover 23, plunger 7 and mechanism 5 extending in a horizontal direction, th exit. or discharge channel 12 preferably inclining downwardly as shown in Fig. 2 tol facilitate the ejection ofthe finished briquet. In the jposition of rest and assuming that the full through the medium of the arms 27 to the position indicated by dotted lines in Fig. 2; in this position the interior of the trough or receptacle 20 is exposed substantially throughoutv itsentire length, the plunger 7 being drawn back as before stated and as also shown insaid Fig. 2. The material to be briqueted, for instance metal or mineral fines, is then fed into said trough either manually or by means of any suitable feeding device until the desired amount has been reached. The cover 23 is thenreturned to its normal position and locked therein by means of the bolt 33 or other locking means, this operation causing said cover 23 to press down upon the material in the trough 20 and forming a fairly well packed mass. The mechanism 5 is now operated to cause the plunger 7 to move forward into the cylinder formed by the' trough 20 and cover 23 at a moderate pressure whereby the material is slowly forced from said cylinder and slowly packed into themold 9 against the plate l1, the speed of operation bein so `gaged as to allow the escape of air said material. When the material has all been pushed or transferred from said cylinder to the mold 9, full pressure is exerted upon the plunger 7 until a solid, homogeneous briquet of even density is formed and a perfect set of" the material is obtained.

As soon as this result has been accomplished pressure is removed from the plunger 7 to relieve the plate 11 which is then raised by means of the lever 13 and counterweight 17 to establish communication between the mold 9 and the exit or discharge channel 12. The plunger 7 is thenvagaln set in motion or caused to move forward in a manner t'o bring sufficient pressure upon the finished briquetto eject it from the mold been fiilly .ejected the plate 111 is again returned to operative position to close the exit end ofthe mold 9 and the plunger 7 is drawn.

back until its end 8 is again located at or in close'proximity to the free end of the cylinder formed by the trough 20-and cover 23. It will, of course, be understood, ifthefull capacity of the trough 20 is not desired, for

9.1n e discharge channel 12 from which 1t ma. ass toa suitable support, receptacle or the-. .:1=1ke. After the finished briquetv has mame? instance because of the initial density of the material which is to be briqueted, that the plunger' 7 need not be fully withdrawn to the position shown and .described in the illustrated example. In other words, the plunger, in its position of rest or at the start may occupy an intermediate position in said trough in which case only a part of the capacity thereof is made use of. Suitable adjustable stops may be provided in the mechanism 5 for cooperation directly with the plunger 7'or the cross-head 7rl to predetermine the position of rest of said plunger. This starting position is always determined by the initial density of the material and thus prevents overloading of the mold 95 After the plunger 7 has reached its position of rest the cover 23 is again swung to its open position to permit the receptacle or trough 20 to be again filled after which the described operation is repeated, this sequence being continuously repeated through out the operation of the machine. During the operation of the machine the locked cover 23 and the closefsliding fit of the end 8 of the plunger 7 forces the material in its entirety to move forward into the mold Qfand prevents any transverse or other unintentional spread thereof.

My improvedv machine in the preferred form operates entirelyy in a substantially horizontal direction and is thus capable of producing briquets of maximum quality while working eliciently at low tonnage capacity. My improved machine also provides for readily feeding the material thereto and for eiiicientlypacking it prior to the usel of the heavy. pressure whereby the actual briqueting 1s accomplished and' in addition provides for the removal of the finished briquet from the machine in a simple and eiiicient manner and without dangerof injuring the briquet itself.

Furthermore my improved machine avoids the necessity for high capacity and expensive installations heretofore generally 'necessary to secure proper working and thus brings the many and well known advantages of briqueting within the reach of small foundries and industrial plants which usually are unable to stand the expense connected with the installation and operation of such machines. My machine may be eiiiciently utilized for briqueting many kinds of material and is particularly adapted for briqueting metal 0r mineral fines without the use of a binder of any description.
